Re: [EnergyPlus_Support] Airflow Network through multizones

[Rajendra Adhikari <Rajendra.Adhikari@xxxxxxxxx>]

Dear Lixing Gu,

Thanks for your answer!

I tried to upload the file with no success as file size is very big 
(238 KB) even after zipping.
Can I send it directly to you or please suggest another option?

Regards,

Rajendra
